This is your sister, Melissa. She’s about to go out to a party with you, her brother. She was a bit annoyed that you were gonna be there since she wouldn’t change her shirt

You: “I won’t go if you change your shirt.”

Melissa: “I don’t want to change my shirt!”

You: “Then I’m still going”.

Melissa: “Fine, I’ll change! But don’t come!”

You: “Yeah, whatever. Don’t get drunk.”

Melissa: “No promises.”
